5.2.9 DATA MEMORY-calibration data
!
Note!
You get to the data memory calibration data by means of the CONFIGURATION menu. In the
"Calibration factor" menu item, press the
J
key.
5.3 Calibration
!
Note!
The calibration is not performed with a hydrazine standard (short shelf life) but with a color
equivalent.
The first calibration step is an offset measurement of a sample (=basic value). After that, the cell is
rinsed with the color equivalent. Finally, color equivalent and reagent are pumped into the cell and
the value is determined (=plateau value).
5.3.1 Standard calibration data
The signal strength is processed device-internally as a frequency.
The following table provides an overview of the standard calibration data.
!
Note!
Compare these values to your own data.
After changes in the CONFIGURATION menu and in the event of software updates, you can check
and, if necessary, change the calibration data in the sub-menu.

This data memory contains the last 100 calibration factors
with date and time. If no values are available, "Empty set"
appears. Browse through the data sets with the
V
and
W
keys.
Serial output
only possible via PC!
No display
You can output all data sets (in ASCII-format) via the
serial interface. For this, the PC must be configured as
follows: 9600, N, 8, 1.
To send data, the PC must send the ASCII character 67
("c").
